The latest AMD ATI roadmaps reveal details of more DirectX 10 graphics cards

DailyTech has just finished its briefing on the upcoming AMD ATI Radeon launches.  The company has three major launches over the next few months: codenamed R600, R610 and R630.

The R600, ATI's ultra-high-end Radeon X1950 successor, has a production date scheduled for February 2007.  The card will launch at or around the Cebit 2007 convention in mid-March.  Shipments will follow shortly after.

Our latest roadmaps indicate R600 will support unified shaders and GDDR4 or GDDR3 memory.  GDDR3 versions of the card running revision "A12" silicon appear to be making rounds in the blogsphere, and select press can even take a sneak peak  of the card under embargo here at CES.  The final silicon for R600 will be "A13."

A GDDR4 version of the card will be the flagship launch product. Clock frequencies on any R600 card have not been set officially yet, and will not appear on marketing material until just a few weeks before the launch.

The company has also added the R610 and R630 GPUs to the roadmap.  In the past, ATI has used lower number codenames to denote entry-level products.  We would suspect R610 would be the entry-level R600 cutdown, and R630 would be the mid-range chipset.  The Radeon roadmap puts both of these products on the shelf before June 2007.

All R600-series GPUs from ATI are compatible with DirectX 10.

From what I have heard is that the Xenon has 64 unified pipelines and 16 have been disabled due to yield issues. Based on that information the R600 can be described as a mixture between R5xx and the Xenon. In this case the R600 has full 512 bit internal ring bus (further development of R5xx) but no embedded DRAM like the Xenon has. There's a question in how the pipelines in the R600 will be grouped, say 64 parallel pipelines or groups of 16? While the Xenon has 3 groups of 16 pipelines, 64 independant groupes is way more efficient (i.e. groupes of 1).

And I think the R600 is not late at all. Vista has yet to arrive at the end of januari and so have the DX10 games. Even than that has to mature.

I thought the Xenon was the CPU not the video card?

I double checked the CPU was called Xenon. The GPU was called Xenos.

Ah thanx, I always mix them up
